Guidelines for the materials selection and corrosion management of downhole production and injection well equipment

This publication provides informative guidance on the corrosion management of downhole equipment for conventional oil and gas production and injection wells, many of which operate at high pressures and with hazardous fluids, by identifying potential corrosion threats and appropriate corrosion mitigation measures. Whilst the focus is on conventional oil and gas production and injection wells, there are some comments on other well types.

The guidance provided in this publication will be of use to duty holders, managers of operations, engineering and maintenance functions and as an introduction for those requiring a basic understanding of the subject. Use of this guidance will ensure that critical issues and options will not get overlooked, leading to a safer and more cost-effective management of the corrosion challenges of well equipment.

The general concepts of corrosion management, organisation and procedures are covered by the EI’s Guidance for corrosion management in oil and gas production and processing.
